Description Modern taxonomy in general is heading towards an integrated approach to taxonomy
(Osterhage et al. 2016), especially in case where ambiguities are to be resolved among highly
cryptic species. Integrated taxonomy compiles and analyse taxonomic information from all the
available resources like classical taxonomy (morpho-meristic features) and modern tools (DNA
based methods). The integrated approach most often provides a better resolution than the
individual methods. Further, the classical approach to taxonomy itself has evolved substantially
and provides much more insights than ever before. Classical taxonomy mostly revolves round
the observation of external characters like major morphometric measurements or counts and
subsequently on anatomical features like neurocranium, facial bones, caudal verterbrae, etc
(Alexandre and Menezes, 2007). At present, in addition to these, even shapes of otolith and
scales have been incorporated in species differentiation and description (Jawad and Al-Jufaili,
2007). The science of taxonomy also changed in the way the morphological data is being
collected. Presently, several images based techniques like truss networks or fourier descriptors
are used to objectively represent the morphometry and shape of the species (Pavlov, 2016;
Renjith et al. 2014; Afanasyev et al. 2017; Gupta et al. 2018). These advancements in the
classical approach to taxonomy and support extended by molecular science are given rise to an
integrated approach to taxonomy, which is now being accepted as best practices in taxonomy.
